Argumentation and Fallacies in Creationist Writings Against Evolutionary Theory Petteri Nieminen1,2* and Anne-Mari Mustonen1
Nieminen and Mustonen Evolution: Education and Outreach 2014, 7:11 http://www.evolution-outreach.com/content/7/1/11 RESEARCH ARTICLE Open Access Argumentation and fallacies in creationist writings against evolutionary theory Petteri Nieminen1,2* and Anne-Mari Mustonen1 Abstract Background: The creationist–evolutionist conflict is perhaps the most significant example of a debate about a well-supported scientific theory not readily accepted by the public. Methods: We analyzed creationist texts according to type (young earth creationism, old earth creationism or intelligent design) and context (with or without discussion of “scientific” data). Results: The analysis revealed numerous fallacies including the direct ad hominem—portraying evolutionists as racists, unreliable or gullible—and the indirect ad hominem, where evolutionists are accused of breaking the rules of debate that they themselves have dictated. Poisoning the well fallacy stated that evolutionists would not consider supernatural explanations in any situation due to their pre-existing refusal of theism. Appeals to consequences and guilt by association linked evolutionary theory to atrocities, and slippery slopes to abortion, euthanasia and genocide. False dilemmas, hasty generalizations and straw man fallacies were also common. The prevalence of these fallacies was equal in young earth creationism and intelligent design/old earth creationism. The direct and indirect ad hominem were also prevalent in pro-evolutionary texts. Conclusions: While the fallacious arguments are irrelevant when discussing evolutionary theory from the scientific point of view, they can be effective for the reception of creationist claims, especially if the audience has biases. Thus, the recognition of these fallacies and their dismissal as irrelevant should be accompanied by attempts to avoid counter-fallacies and by the recognition of the context, in which the fallacies are presented. -
Common Reasoning Mistakes
Common Fallacies (mistakes of reasoning) The fallacy fallacy • There is danger even in the study of fallacies. This study involves identifying certain patterns of reasoning as fallacies. Each pattern has a name. E.g. an argument that attacks a person is ad hominem. But ad hominem arguments are not always fallacies! • Rejecting an argument as a (named) fallacy, based on its pattern alone, is a fallacy that we might call the fallacy fallacy. • In general, an ad hominem is only legitimate when attacking an argument from authority. • But not all such attacks on authority are legitimate. They can be made on irrelevant grounds. Irrelevant ad hominem E.g. Einstein’s physics was attacked on the basis of Einstein being Jewish. Thomas Powers, Heisenberg’s War, p. 41 Fallacy? • Alliance leader Stockwell Day argues that Canada should increase its military expenditure now, by at least 20%, in order to continue to meet our NATO obligations five years from now. But Day is a fundamentalist who thinks the universe is only 6,000 years old! Clearly his view can be dismissed. • Mr. Wilson, in his letter of January 16, argues that it would be counter-productive to yield to the demands of the hostage takers. He does not, I take it, have a son or daughter among the hostages. As such a parent, I am repelled by his callous attitude. My daughter could well be the next innocent victim of these terrorists, but Wilson apparently doesn’t give a damn about this. 1. Comment on the following ad hominem (to the person) arguments, explaining why they are, or are not, reasonable. -
Explicit Examples of Logical Fallacies in Love Is a Fallacy by Max Shulman Foundations – Part of the Easy Peasy All-In-One Homeschool
Explicit examples of logical fallacies in Love is a Fallacy by Max Shulman Foundations – Part of the Easy Peasy All-in-One Homeschool A dicto simpliciter ("an argument based on an unqualified generalization") - the example given in the story is: Exercise is good. Therefore everybody should exercise. Hasty generalization (or "fallacy of insufficient sample") - example given in the story is “You can speak French, I can't speak French, Petey Burch can't speak French. I must therefore conclude that nobody at the University of Minnesota can speak French.” If most of the people the author (Dobie Gillis) knows cannot speak French he concludes that no one at the college can speak French. OR "My dear," I said, favoring her with a smile, "we have now spent five evenings together. We have gotten along, splendidly. It is clear that we are well matched." Post hoc ergo propter hoc ("after it, therefore because of it", or "confusing coincidental relationships with cause") - from the story: “Let's not take Bill on our picnic. Every time we take him out with us, it rains.” Contradictory Premises ("self-contradiction") - from the story: I do not see the contradictory premise in this story. The main contradiction would be that the author (Dobie Gillis) begins the story believing that love is logical and can be won through logic. However, the end of the story proves that love is not logical and Dobie’s original belief was a fallacy. Ad Misericordiam ("appeal to pity") - example given in the story: "A man applies for a job. When the boss asks him what his qualifications are, he replies the he has wife and six children at home, the wife is a helpless cripple, the children have nothing to eat, no clothes to wear, no shoes on their feet, there are no beds in the house, no coal in the cellar, and winter is coming." OR “Polly, I love you. -

ALABAMA STATE UNIVERSITY DEPARTMENT OF LANGUAGES AND LITERATURES COURSE SYLLABUS PHILOSOPHY 201 LOGICAL REASONING (PHL 201) (Revised 10/20/04 – Dr. Daniel Keller.) I. Faculty Listing: PHL 201: Logical Reasoning (3 credit hours) II. Description: To satisfactorily complete the course, a student must earn a grade of “C.” The course is designed to help students assess information and arguments and to improve their ability to reason in a clear and logical way. The course concentrates specifically on helping students learn some of the various uses of languages, understand how different kinds of inferences are drawn, and learn to recognize fallacies of ambiguity, presumption, and relevance. III. Purpose: Many students do not reason soundly and do not distinguish correct from incorrect reasoning. Hence, the aim of this course is to give students experience in learning to recognize and evaluate arguments; it also aims at teaching them to construct arguments that are reasonable and defensible. It is designed as a basic course to improve the reasoning skills of students. After completing this course successfully, students should show improvements in reading comprehension, writing, and test- taking skills. IV. Course Objectives: 1. Comprehend concepts 1-9 on the attached list. a) Define each concept b) Identify the meaning of each concept as it applies to logic. 2. Comprehend how these concepts function in logical reasoning. a) Given examples from the text of each concept, correctly identify the concept. b) Given new examples of each concept, correctly identify the concept. 3. Comprehend concepts 10-16 on the attached list. a) Define the concepts b) Identify the meaning of the concept as it applies to logic. -
Should Climate Scientists Fly? a Case Study of Arguments at the System Level Jean Goodwin
Document generated on 09/26/2021 2:33 a.m. Informal Logic Should Climate Scientists Fly? A Case Study of Arguments at the System Level Jean Goodwin Volume 40, Number 2, 2020 Article abstract I inquire into argument at the system level, exploring the controversy over URI: https://id.erudit.org/iderudit/1070883ar whether climate scientists should fly. I document participants’ knowledge of a DOI: https://doi.org/10.22329/il.v40i2.6327 skeptical argument that because scientists fly, they cannot testify credibly about the climate emergency. I show how this argument has been managed by See table of contents pro-climate action arguers, and how some climate scientists have developed parallel reasoning, articulating a sophisticated case why they will be more effective in the controversy if they fly less. Finally, I review some strategies Publisher(s) arguers deploy to use the arguments of others against them. I argue that only by attending to argument-making at the system level can we understand how Informal Logic arguers come to know the resources for argument available in a controversy and to think strategically about how to use them. I call for more work on ISSN argument at the system level. 0824-2577 (print) 2293-734X (digital) Explore this journal Cite this article Goodwin, J. (2020). Should Climate Scientists Fly?

The coordinator of this project is MITRA FRANCE non-governmental organization from France. The project is funded by the Erasmus+ Programme of the European Commission. It seeks to develop initiatives addressing spheres of adult education, gathering and exchanges of experience and best practices in media literacy. This initiative contributes to strengthening media literacy as a mean of countering online and ordinary radicalisation and stigmatisation. As one of the results of this partnership the consortium has compiled a Toolkit with several good practices exchanged and tested during this project. This Toolkit is designed for adult educators, trainers and support staff who are interested in using media literacy in their daily work. -
Christ-Centered Critical Thinking Lesson 7: Logical Fallacies
Christ-Centered Critical Thinking Lesson 7: Logical Fallacies 1 Learning Outcomes In this lesson we will: 1.Define logical fallacy using the SEE-I. 2.Understand and apply the concept of relevance. 3.Define, understand, and recognize fallacies of relevance. 4.Define, understand, and recognize fallacies of insufficient evidence. 2 What is a logical fallacy? Complete the SEE-I. S = A logical fallacy is a mistake in reasoning. E = E = I = 3 http://1.bp.blogspot.com/-o9VE5tseuFk/T5FSHiJnu7I/AAAAAAAABIY/Ws7iCn-wJNU/s1600/Logical+Fallacy.JPG The Concept of Relevance The concept of relevance: a statement for or against another statement. A statement is relevant to a claim (i.e. another statement or premise) if it provides some reason or evidence for thinking the claim is either true of false. Three ways a statement can be relevant: 1. A statement is positively relevant to a claim if it counts in favor of the claim. 2. A statement is negatively relevant to a claim if it counts against the claim. 3. A statement is logically irrelevant to a claim if it counts neither for or against the claim. Two observations concerning the concept of relevance. 1. Whether a statement is relevant to a claim usually depends on the context in which the statement is made. 2. A statement can be relevant to a claim even if the claim is false. 5 Fallacies of Relevance • Personal attack or ad hominem • Scare tactic • Appeal to pity • Bandwagon argument • Strawman • Red herring • Equivocation http://www.professordarnell.com/wp-content/uploads/2012/05/fallacies.jpg • Begging the question 6 When a person rejects another person’s argument or claim by attacking the person rather than the argument of claim he or she commits an ad hominem fallacy or personal attack. -

Master List of Logical Fallacies
Master List of Logical Fallacies Fallacies are fake or deceptive arguments, arguments that prove nothing. Fallacies often seem superficially sound, and far too often have immense persuasive power, even after being clearly exposed as false. Fallacies are not always deliberate, but a good scholar’s purpose is always to identify and unmask fallacies in arguments. Ad Hominem Argument: Also, "personal attack," "poisoning the well." The fallacy of attempting to refute an argument by attacking the opposition’s personal character or reputation, using a corrupted negative argument from ethos. E.g., "He's so evil that you can't believe anything he says." See also Guilt by Association. Also applies to cases where valid opposing evidence and arguments are brushed aside without comment or consideration, as simply not worth arguing about. Appeal to Closure. The contemporary fallacy that an argument, standpoint, action or conclusion must be accepted, no matter how questionable, or else the point will remain unsettled and those affected will be denied "closure." This refuses to recognize the truth that some points will indeed remain unsettled, perhaps forever. (E.g., "Society would be protected, crime would be deterred and justice served if we sentence you to life without parole, but we need to execute you in order to provide some sense of closure.") (See also "Argument from Ignorance," "Argument from Consequences.") Appeal to Heaven: (also Deus Vult, Gott mit Uns, Manifest Destiny, the Special Covenant). An extremely dangerous fallacy (a deluded argument from ethos) of asserting that God (or a higher power) has ordered, supports or approves one's own standpoint or actions so no further justification is required and no serious challenge is possible. -

Logical Fallacies Summed up 1:23:20
Logical Fallacies Summed Up Good arguments are claims based on reasoning that is Clear, Accurate, Relevant and Sufficient. Fallacies of Glittering Generality A vague, richly emotive term with no clear meaning. Unclear Evidence Equivocation A critical word/term in the argument is not used consistently. Questionable Premise The argument’s claim is based on an unproved premise or premises. (Premises are reasoning/evidence.) Includes outright lies, etc. Begging the Question The very thing the controversy is about is assumed true. Fallacies of Complex Question Loaded question (includes a questionable premise). Evidence of Circular Argument Unproved propositions/claims are used to prove each other. Questionable Either-Or fallacy “False Choice:” limited alternatives are presented, when they are Accuracy not mutually exclusive or more options should be considered. Strawmanship A position is misrepresented in order to better attack it. Accent Evidence is distorted by a change in emphasis, it is taken out of context, or significant factors are not mentioned, etc. Irrelevant Argument Argument presented that is irrelevant to the topic at hand. Non-Sequitur It does not follow (proof/reasoning irrelevant to the claim). Argument from Ignorance Arguing that a claim is true simply because it has not been proven false (or vice-versa). Attempts to switch the burden of proof. Ad Hominem Fallacy Attacking the arguer instead of the argument/reasoning. Attacking a personal characteristic (character, competence, etc.) of • Ad Hominem Abusive an opponent instead of refuting the opponent’s reasoning. Because of an arguer’s personal stake in the matter, or a position • Ad Hominem Circumstantial taken previously, the arguer is attacked instead of the reasoning.
